And now -- Mitt super PAC hits Santorum over the phones

3/6/12 3:28 PM EST

We've reported in this space on Restore Our Future's anti-Santorum TV ads and the super PAC's four (at least) mail pieces in next Tuesday's Alabama and Mississippi primaries.

Now, sources tell me ROF is running robo-calls against Santorum in both Alabama and Mississippi — a pair of states where the former Pennsylvania senator must do well to gain momentum after Super Tuesday.

The script, per a source who recorded the call in Alabama:

Rick Santorum said on Fox News that he’s “proud” of all the earmarks he put on bills as a U.S. senator. Can you imagine? Being proud of the type of spending that helped drive our country to the brink of financial disaster? Rick Santorum has a history of wasteful government spending and favoritism at taxpayers’ expense. We can say no to wasteful government spending. On March 13, say no to Rick Santorum. Paid for by Restore Our Future and not authorized by any candidate or candidate’s committee.

A ROF strategist confirmed the group is running calls in Mississippi as well. For those keeping score at home, that makes a pretty full-scale campaign operation working on Romney's behalf in both March 13 states.
